Looking at the console it says connection refused. Maybe it's something from chrome, I'll try Firefox to see if I have the same problem there 

 Using Firefox worked 

 Maybe this is something you can fix by checking the relay connection after a few seconds when reopen the subscription if it got disconnected? 

 Yeah, I got that logic in nsec.app, need to repeat on nostr-login. At least you can just refresh the page to make it reconnect.
